Summary

Converts a bitmap to rich text format.

run\JvRichEdit.pas

Pascal

 run\JvRichEdit.pas

 procedureBitmapToRTF(ABitmap: TBitmap; AStream: TStream);
functionBitmapToRTF2(ABitmap: TBitmap; AStream: TStream): Boolean;

Parameters

Parameters	Description
ABitmap: TBitmap	The bitmap to convert.
AStream: TStream	Stream where to save the RTF data to.

run\JvRichEdit.pas

Description

Use the BitmapToRTF or BitmapToRTF2 procedures to insert bitmaps in a rich edit control. BitmapToRTF2 returns true if the bitmap is written to stream as RTF, or false if an error occurred.
For example, to replace the selected text with a bitmap, do the following: Stream := TMemoryStream.Create;


   try

     BitmapToRTF(SomeBitmap, Stream);

     Stream.Position := 0;

     JvRichEdit1.StreamFormat := sfRichText;

     JvRichEdit1.StreamMode := [smSelection, smPlainRtf];

     JvRichEdit1.Lines.LoadFromStream(Stream);

   finally

     Stream.Free;

   end; 

• If you stream out the RTF content of the rich edit control, the bitmaps are not included. Use InsertGraphic if you want the bitmaps to be includedin the streamed out RTF data.
• TJvRichEdit.AllowObjects must be set to true.
• BitmapToRTF is the fastest, InsertGraphic the slowest.
